支持informixreader吗，可以配置吗？

可以用rdbmsreader配置informix吗？
1、我在rdbmsreader的plugin.json中配置
"drivers":["dm.jdbc.driver.DmDriver", "com.sybase.jdbc3.jdbc.SybDriver", "com.edb.Driver", "com.informix.jdbc.IfxDriver"]
2、libs下放了ifxjdbc.jar
3、job的配置如下
"reader": {
"name": "rdbmsreader",
"parameter": {
"username": "",
"password": "",
"connection": [{
"querySql": [
"select userid,departid from user_depart where userid=1;"
],
"jdbcUrl": [
"jdbc:informix-sqli://ip:port/database:INFORMIXSERVER=;"
]
}]
}
},
4、运行job报错
配置信息错误，您提供的配置文件xxxx/xxxxx/xxx/plugin.json不存在，请检查您的配置文件。

Start with ConfigParser.parsePluginConfig and ConfigParser.parseOnePluginConfig, where the reported missing plugin.json error occurs. Compare the rdbmsreader plugin.json and libs/ifxjdbc.jar setup with the supplied job configuration, then verify whether the Informix driver is recognized and the job can execute the query without the configuration error.
